Speedmaster magnum inspection w/Justin
So you guys know I ordered up a set of their cast-iron Magnum replacement heads supposed to be 179 cc's. I ordered them one at a time in case they were less than workable/too much effort.
So the 1st head shows up, covered in machining lube splatter and or silica.
I looked it over and the port looked taller..larger..but had a jacked vj undercut and tiny stock port window 'pinches' with not much if any ability to open then up for a thumb to even fit through...in fact.. it had stock matkings like the fin on the intake floor. Still figured @ a 2.02 i could muster 250 mayne 260cfm.. now.. i bought these for my truck, keep in mind, so i didn't have a pocket full of expectations of these.. therefore was happy with that possible outcome. Here are those pics..
I have... good?.. news though....but there is still something i see in the pics now that im typing this. Port volume.
